GM Outlaw Torque Converters

The Torque Converter is considered to be the most mysterious mechanical component in today’s vehicle. It functions like a clutch, which keeps the motor running even when the vehicle comes to a halt. By designing the stall speeds to matchboth the engine and desired stall speed, an ACC Performance converter will help low-end idle speeds, improve performance and acceleration. We can drastically change the output of the vehicle. ACC Performance can even improve your gas mileage by modifying your torque converter. ACC Performance Torque Converters feature several uses in different industries like industrial power transmissions, automatic transmissions, trucks, buses, and many other applications that include everything from race vehicles to rock crawlers. Proper installation, maintenance, and protection are needed for the torque converter to obtain the longest life possible. A default in the maintenance or heat protection of the torque converter can result in damage such as overheating, stator clutch breakage, fin damage, ballooning, and stator clutch seizure. It is imperative that a transmission cooler be added with any torque converter that is rated over a stock stall.

In a high performance application the so called “transmission cooler” that runs through the radiator is in all actuality a transmission fluid heater. The internal radiator transmission cooler will raise the temperature to normal operating temperature much faster. This make the transmission fluid flow much easier throughout the transmission giving you better fuel mileage. However, the temperatures that the radiator hits does not allow for the proper cooling properties that are needed with today’s high performancetransmissions. Most radiators have an operating temperature of about 200 degrees. There must be a 34.7 degree variance in temperature before an acceptable amount of cooling can occur. The proper way to insure that the correct amount of cooling is taking place would be to by-pass the radiator and go through an external transmission cooler. ACC Performance suggests a minimum of a 3/4” X 10” X 12” size cooler. The addition of an external transmission cooler can drop the transmission fluid temperature more than 10 degrees which can more than double the life of your transmission.

All torque converters operate off of the twisting force of the engine and fluid pressure versus the weight of the vehicle. Do you remember back when you put dual exhaust on a truck and it got a little better gas mileage and engine performance? Well, the reason is: It freed up the exhaust to a point that it would expand the RPM range with the better exhaust flow. It would even give you better midrange and upper RPM power. It also lowered the torque between idle and 2,400 RPM. This change in the pressure on the transmission fluid would lock up the sprag in the stator earlier. You would have to say that the converter locking up earlier allowed the vehicle to move with less RPM. This in turn will give the vehicle better mileage and upper RPM performance.

What makes ACC Performance torque converters better than the rest?
Selling the highest quality Torque Converters since 1971 because we care.As of October 2005 ACC Performance took on a new owner who brings Aircraft Engineering and Quality to the High Performance Torque Converter Industry. ACC Performance uses “World Class Manufacturing”, combined with “Just in Time Manufacturing”, to get you the highest quality parts available combined with impeccable delivery times.

The automotive industry now has a new Torque Converter Leader. ACC Performance Products has emerged as an out-right leader in this industry and here’s why:

• The Original BOSS HOG is Welded, not Furnace Brazed (unless requested): Contrary to popular belief, furnace brazing is not the best way to adhere torque converter components together. Just like a Teflon coated cooking pan, after some time the furnace brazing will erode away and ruin the stators and all other rotating parts in your transmission. All BOSS HOG Torque Converters are welded at the fins, not brazed, to eliminate the erosion after time.
• We use Industrial Torrington Type Bearings: No Light Duty Bearings Needle bearings are good, but not great. Industrial bearings give these converters the ability to handle not hundreds, but thousands of pounds of torque.
• Aircraft Aluminum Washers: ACC Performance Products Torque Converters utilize an aircraft quality aluminum washer instead of those old fiber washers that other companies use. This will put more horsepower and torque directly to the ground.
• Every BOSS HOG is Hand Built: All ACC Converters are hand built and tested to ensure that you are getting the best converter money can buy! No automated process can ensure that kind of quality.
• Returns Are Almost 0: With our returns being below 1%, you are assured that you have the highest quality parts that are available on the market.

Outlaw Series Converters handle up to 1,000+ hp

The Outlaw Series Converters will handle as much as 1,000+horse power.

The Outlaw Torque Converter is the toughest ACC Performance Torque Converter built. All of the Outlaw series Torque Converters come with a custom Anti-ballooning plate that is designed to hold back any potential ballooning of the Torque Converter. These special designed plates keep the extra weight off of the rotating mass. The Outlaw series converters are designed to handle the extreme shock and abuse of excessive horse power, Nitrous Oxide and or Trans-Break.

ACC Performance puts the much larger Torrington type incased bearings through out the converter where the weaker points are. The Torrington bearings will handle a lot more raw power and abuse that the higher horse power engines and transmissions of today produce. Some of the competition uses a smaller needle type bearing. Needle bearings are not incased, which makes them susceptible to picking up trash in transmission fluid, which can lead up to heat build up and failure.

We also weld-up and tack-weld our turbine and impeller fins all the way around in order to maintain the highest strength. This will stop fin degradation or deformity. We also have custom engineered turbine hubs in order to maintain the highest quality, strength, and durability. Some of the competitors use a chromemoly steel turbine hub that does not weld very well. If improperly welded, it can cause converter failure and or damage to your transmission.

The ACC Performance stators are built to handle more power and heat ranges The stators are built with high flow vents and channels for greater cooling in order to handle the much greater power and heat ranges.

ACC Performance converters are engineered with a single bolt pattern for the rotating mass. This makes ACC Performance Torque Converters surprisingly light, keeping the weight of the converter off of the rotating mass of the motor. This will free up your motor and allow it to rev-up through the RPM range quicker, helping your engine put more power to the ground. Some of the competitors use a dual bolt pattern converter to eliminate multiple part numbers, i.e./ th350 & 400’s. These transmissions using the same converter with a dual bolt pattern, will add 3 to 4 pounds of weight to the converter. This adds weight to the rotating mass of the engine, costing you nothing but horsepower & torque. We at ACC are in the performance business and try to maximize horsepower at every level. We think you do too!

Picking the stall range for your Restoration or Street Vehicle can be a little tricky. Cataloged stall ranges are picked by the vehicle’s basic set-up (i.e. horse power, engine torque, vehicle weight, etc.). The stall range will vary from car to car. This means, the converter must be matched up to fit your specific vehicle’s set up. A built engine with all the goodies will need more stall in order for the engine to idle correctly. We would suggest you consider one of our Night Stalker style converters.

If you have engine modifications, intake, cam or a modified exhaust system, then you may want to give our techs a call at (888) 267-7464. Changing the weight of the vehicle will affect the stall. Let us help you pick the torque converter for your vehicle.

Example: Let’s take a street rod that weighs 1,900 lbs to 2,400 lbs. The weight of the vehicle will drastically reduce the stall of the torque converter. To set a stall on a 1900 lb. street rod at 1,800 rpm, you would need a converter with a stall speed of around 5,000 rpm.
